'This invention relates to a window sash con- "struction, and one of theobjects of the invention is to provide a vertically sliding sash withmeans for maintaining it in various vertical positions by springfriction, without the use of balancing weights.

Another object of the invention is the provision of a sliding sash withan inner frame, which is hinged to swing inwardly and downwardly, sothat the outer side of the window pane may be accessible from theinterior of a room, and cleaning thereby made easy and safe.

With the above and other objects in view the invention comprises certainnew and useful constructions, combinations and arrangements of parts,clearly described in the following specification, and fully illustratedin the accompanying drawings, in which:

Fig. 1 is a perspective View.

Fig. 2 is a vertical sectional View, showing the hinged inner sashsection or frame in dotted lines,

in its cleaning position.

Fig. 3 is a horizontal sectional View, taken on line 3-3 of Fig. 1,looking in the direction of the arrows.

Fig. 4 is an enlarged vertical sectional view, taken on line 4-4 of Fig.3, looking in the direction of the arrows.

Fig. 5 is a horizontal sectional view, taken on line 55 of Fig. 4,looking in the direction of the arrows.

Fig. 6 is a detail sectional view through the hinge connection betweenthe inner, pane carrying sash section and the outer sliding framesection.

Fig. '7 is a perspective view of a portion of the frame and sashmembers, separated to disclose the pivot pin details.

Referring to the accompanying drawings, which illustrate the practicalconstruction of the invention, 5 designates a window frame construction,which includes the right casing section 6 and the left casing section 8,which are connected in the usual manner by the sill 9.

The casing section 6 is equipped with a vertical channel member II],which includes the opposing and parallel side flanges II and I2. Midwayof these side vertical flanges II and I2 a narrow channel bar or-memberI3 is connected to the base wall of the channel member or bar II]. Theleft casing section 8 is provided with a similar channel member or barIt, constructed with an intermediate channel bar similar to the bar I3.The bars or members IE] and I4 are disposed in opposition to each other,in the verti- I cal positions usually occupied-by the parting strips ofstandard window frame constructions.

A guide strip I5 is securedagainst-theouter flange I2 of each channelbar or -member, and. a supporting strip I6 against each inner flange IIAn upper sash II slides between the right and left casing sections, anda lower sash I3 also slides between these two casing sections. The uppersash is equipped on each side with a T-shaped angle strip or bar I9,which provides the intermediate vertical flange 2B, which slida-blyengages the outer flanges I2 of the opposing channel bars I0 and I4. Thelower sash is equipped on each side with a similar T-shaped angle bar2|, which provides the intermediate vertical flange 22, which slidablyengages the inner flanges I I and I2 of the channel bars I!) and I4.

The intermediate channel bar I3 .of each main channel bar, I0 and I4,carries a plurality of vertically spacedmand horizontally mountedsliding rods 23, each one of which is engaged by an expansion coilspring 2s, the inner end of each spring engaging a pin or stop 25 on therod. The inner ends of these rods are provided with convex button heads26, which are designed to have direct abutting engagement with eachother. The outer ends of these pins are provided with rounded bearingheads 21 which slidably engage the vertical flanges 2B of the uppersash. .A duplicate set of reversed spring pushed sliding rods 28 is alsocarried by the intermediate channel bars I3, and the outer end of eachof these rods 28 is provided with a rounded bearing head I 29, which isadapted to slidably engage the vertical flanges 22 of the lower sash.The arrangement is such that when one sash is moved by raising orlowering it, the outer ends 21 of slidable horizontal rods 23 engageagainst flange 20 of the lower sash, urging the rods in opposition totheir springs to engage by their heads or but- I tons 26 against thecorresponding inner heads or buttons of rods 28 until the sash hasreached a position such as shown in Figure 4, wherein the heads 21register with apertures 21a in flange 20. In this position, the headswill partly enter said apertures and determine a closed position of thesash, and will frictionally resist opening of the sash by offeringresistance to being shifted out of apertures 21a onto the flat unbrokenportion of the flange. As these apertures may be equidistantly spacedapart, they also determine several more or less open positions of thesash.

In similar fashion, the other sash is also frictionally retained inclosed or in different open positions by cooperation of rods 28 andtheir heads 29 with apertures 29a in flange 22. In each case, thesprings tend to urge the inner buttons of each pair of rods against eachother, so that when either sash in movement shifts either set of rods byforcing the outer heads thereof out of their respective apertures, suchshifting of the related rods will be transmitted thereby through thebuttons 26 thereof to the other rods and tends to cause the latter to belocked frictionally with the apertures on their side, the result beingthat the corresponding sash is prevented from shifting or being opened.

The spring pressure applied by the rods 23 and '28 against the verticalflanges'zfi and 22 establish sufficient friction to exceed the pressureof the sashes to produce sliding movement, with the result that eachsash will be held by friction alone in the position of its manualadjustment.

Each sash includes a main sliding section 3% and an inner section 3!pivotedor hinged thereto, as will be explained, and which carries theglass window pane 32, mounted in the usual manner, as by putty 33. Theinner sash section 3! fits between the side members 39 of the main sashsection, and is r of corresponding thickness throughout, so that noportions will project laterally from the main sash section, in eithervertical plane.

The inner sash section 3i is hingedly connected to the side bars 35a and3% of the main sash section 38, by means of the hinges 3d, in the mannershown in Fig. 6. These hinges are located near the lower end of theinner sash section, and so arranged that the inner sash section willswing inwardly and downwardly on the axis of the hinges. The inner framesection 3| is prevented from excessive downward swinging by means of thefolding brace members 35 and 35, which are pivoted to each other andpivoted to the inner sash section and the main sash section,respectively. At 3? on hinged sash locking wedge is provided at eitherside of the upper sash. In order to assist in maintaining the outerportions I1, I8 of the sashes in line and in preventing them fromswinging with the sash frames 3|, they mutually engage in tongue andgroove relation as noted at 33.

By swinging each inner sash section downwardly the outer face of eachwindow pane may be easily and safely cleaned from the interior of theroom. This pane may also be opened to permit fresh air to flow into theroom in an upward direction, as the inclined pane would serve as adeflective surface for directing the moving air to flow into the room inan upward direction, thus providing room ventilation without drafts.

It is understood that various'changes in the details of construction,their combination and arrangement, may be made, within the scope of theclaim hereof.

Having described my invention, I claim:

In combination with a window casing having vertical side members, achannel bar on each side member providing opposite rigid verticalflanges disposed in vertical planes, an upper sash having a verticalflange on each side thereof in a position to have sliding engagementwith one vertical flange of each of the channel bars, a lower sashhaving a vertical flange on each side thereof in a position to haveSliding engagement with the other flange of each channel bar, andresiliently urged means slidably carried by each channel bar formaintaining spring pressure on the vertical flanges of both sashes tomaintain them in vertically adjusted position by the frictionalresistance between the engaging flanges in which the resiliently urgedmeans includes a series of horizontally slidable rods mounted in each ofthe two vertical flanges of each channel bar, the rods associated withone flange having springs urging them against the inner ends of the rodsassociated with the other flange, the outer ends of each series of rodsbeing directed toward the vertical flange of one of the two sashes, theflanges of both sashes having aperture portions with which therespectively adjacent rods will register in several positions of saidsashes, the aperture portions determining said positions and the spacingbetween the flanges of these sashes being positioned so that when therods associated with one flange of the channel bar engage against theflange of the adjacent sash, said latter rods push the rods of the otherseries frictionally against the flange of the other sash, with theresult that each set of rods tends to push the other into engagementwith the apertures in the associated sash flange when these aperturesare shifted into register with said rods by movement of the sashinvolved.
